TO ALL PERSONS TO WHOM THESE PRESENTS MAY COME: v

Be it known that I, KNUD MARKUSON, of Gloucester, in the county of Essex, and State of Massachusetts, have invented a new and useful Improvement in the Handles for Pumps of Navigable Vessels; and do hereby declare the same' to be fully described in the following specification, and represented in the accompanying drawings, of which'-' Figure 1 is a top view,

Figure 2a side elevation,

Figure 3 a longitudinal section, and

Figure 4 a bottom view of a pump-handle provided with my invention.

Figure 5 is un under side view of it, as it appears with one portion, A, folded around upon the other part, i

B, of such handle. l

The said handle, instead of being in one entire bar, as it is customary to make it, I construct in two sepa-- rate parts, A B, the portie-n A being much longer than the part B. To these two partsAB- Iapply two hinges,-

a b, so made that their joint-pins c c may be easily withdrawn from the interlocking partsiof the leaves of such hinges. O'ne hinge I apply and fasten to one, and the other to the opposite side of each of the partsA B, the

same being in manner as represented in the drawings. By removing either of the joint-pins ce of 'either hinge from such hinge, -the longer part Amay be turned around so as to lie alongside of that side of the shorter part B to which the entire hinge may be fixed. This enables the greater part of the handle to be moved out of the way of the boom of the vessel, or to. be stowed across the railing which usually goes around the pumps of a vessel. A shouldered standard or pin, G, is hinged tothe lower side of the part B of the handle. The shank e of the said standard C is to be inserted in a hole made in the saidA rail, in order that the stundardiand rail may support the pump-handle while in operation. The two parts A B of the handle may he connected by one hinge only, Aapplied to the next t-wo adjacent sides of them, a hasp and staple, a catch or lock of some kind, being applied to the opposite sides of the said two parts, in order to hold them in alignment with each lother, but I prefer the additional hinge for such connection, as when two hinges are employed on opposite sides of the parte A B,'an additional advantage is gained, for then the handle will be applicable to either pu'mp, or can have its longer part A turned around against either of the two sides of the shorter part B, as circumstances may require.. A rod, D, having an eye, f, at its outer end, and a square or hat head, g, at its inner end, is arranged in a groove made lengthwise in the inner side of the part B, and is supported by and so as to be capable of being revolved in two staples, h z, fixed in the part B. The head of the rod enters a corresponding recess, z', made in the part A, such head and recess, when the former is within the latter, serving to prevent thcrod from being revolved, and thus operating to preserve it in connection with the hook ofA thc rod 0f the pump-.piston or upper box. When, however, the part A of thehandle is turned out ot' line with the part B far enough to withdraw the recess t' entirely from the head of the rod D, such rod will be free to be revolved as far as may be necessary to facilitate the disengagement of it from the hook of the pump-piston.

- My improvement saves the necessity of removing the pump-handle from the pump in order to stowisuch handle out of the way of the boom or persons. on shipboard. It insures the pump-handle being in connection with the pump, and thus prevents itI frombeing mislaid or washed overboard.

What I claim as my invention is The improved pump-handle, as made in two parts, A B, connected together by two hinges, or by a hinge and latching or locking devices, applied to their opposite sides, the whole being substantially as specied.

I also claim the arrangement and combination of the rotary rod, made as described, and the socket for `the head of such rod, with the two handle-parts, A B, connected substantially as explained.

' KNUD MARKUSON.
